Lecture 5

These flashcards cover key concepts related to biological systems, health span, lifespan, and physiological measurements.

Lifespan

The total number of years an individual lives, on average around 81 years in Canada.

Health Span

The number of years spent in good health, free from diseases that significantly impact daily living.

Homeostasis

The body's ability to maintain a stable internal environment despite changes in external conditions.

Electrical signals that travel along neurons, occurring in milliseconds.

Enzymatic Reactions

BMI

Body Mass Index, a measure of body fat based on height and weight.

Biomarkers

Indicators of the biological state of an organism, used to track health and disease.

Kyphosis

Curvature in the spine, often associated with osteoporosis.

HDL Cholesterol

High-Density Lipoprotein cholesterol, known as 'good' cholesterol that helps to clear plaque from arteries.

LDL Cholesterol

Low-Density Lipoprotein cholesterol, known as 'bad' cholesterol that can lead to plaque buildup in arteries.

Growth Charts

Tools used to assess a child's growth over time, developed by the World Health Organization.

Osteoporosis
